I have a system with an AMD RX 570, and the various kernel 6.4 releases
I've tried all kill video output - it looks like the kernel DRM doesn't
see the monitor at all. Even before it gets to X, if I take "rhdb
quiet" off the boot line, I get kernel messages up until it tries to
switch to the framebuffer mode, I lose video then.
I filed a RHBZ bug against the kernel (since that's where I think the
problem is):
https://bugzilla.redhat.com/show_bug.cgi?id=2224594
But I haven't gotten any response; I understand kernel devs are busy,
not complaining about them, but I was wondering if there might be a
better place to go. I can test things, share more logs/info/etc., just
need some direction.
